Ferdinand endured an injury-plagued last campaign due to back-related problems and then missed the World Cup finals due to a knee injury.
The England captain hurt ligaments in training prior to the start of the tournament, but is now ready to make his comeback for United.
He is expected to be involved in the Red Devils' opening Champions League group game against Rangers on Tuesday and is looking forward to his return.
"I have been training full pelt with the team the last two weeks and played a reserve game the other day and feel good," said Ferdinand in The Sun.
"I just enjoyed being out there, putting the shirt on and smelling the cut grass again."
The 31-year-old added: "My back is fine now. There are things I have to do to make sure the problem doesn't reoccur, but that is all part of getting older.
"I hope I am through it all now. I feel confident my knee is perfect and confident with my back."
